, IThis inventio'n relates to loading machines and moreparticularly to improvements in the material gathering means of machines or similar loose material ,in

means of the machine in an improved and moreeffective manner. A furtherobject is to provide, improved material gathering means ofthecharacter Wh GI'GIII the material "is gathered and moved onto the conveying means by .a shovelingiaction. A further objectis to provide improved gathering means of the aforesaid characterwherein a shovel blade is employed and havingasso ciated therewith improved means for i'mparting to the shovel blade a shovelingmo? tion. ,Still anotherobject is'to providean improved gathering mechanism fora coal loading machine Wherebythe loose coal is" gathered' and moved,v onto the conveying means in an improved'manner and whereby the standin'gcoal at the face-may be undermined and broken down onto the shovel and move'dionto the conveying means of the macl iine. These and other objects of the i nv v les s -flight elevating conveyor 8 with which theimproved material gathering mechanism generally designated 9 cooperates in the loading of the material acted upon thereby;

particular type oi loading. machine with which fthe improved material gathering mechanism'is' associated is not of primary importance and asthe improved gathering mechanism may bencorporated in loading machines of 'various types, details of the machine as an entirety are not'dlsclosed herein. 'The machine disclosed herein generally consistsof a wheeled truck fl having truck wheels 2' adapted to run along a mine track 3. Mounted on'thei truck is a frame 4 confined to horizontal swinging movement relative to thetruck as is' usual in machines of the type disclosed and having pivotally' mounted thereon atfi for vertical swinging movement rawframe 6 terminating at its forwardiend in a shovel 7'. Gr uided on the frame 4' and" the shovel frame 6 is .an end- In" the present construction, carried by the frame :4 is a motor 10 having fixed to its 2) fixed to a transverse shaft 13 suitabl journaled within "the frame 4. 'The'sha t 13 drives through a train of spurl ge'ars14, 15 and 16, a" horizontal shaft '17, herein arranged parallel with and above the shaft 13 and likewise suitablyjjournaled within the frame 4. Fixedlto thisshaft are spr0ck-.

ets 18, l8'whijch engage and dr'ivefthe side chains 19,119 of the conveyor 8. It will thus be 'seen that during running of the motor 10the'gathering conveyor 8 is rapiding longitudinally of the machine at oppoly circulated within its guides. As previously mentioned, the detail construction. of the machlne as a whole is not of prlmary importance and therefore further descrip tion thereof is thought unnecessary. Now referring to the improved gathering mechanism 9, it will be noted that extendplane passing through the axis of rotation of the blade to form transverse penetrating edges'24 and 25. As shown in Fig. 7 formed at the ends'of the double convex portion of the'shovel blade 22 are stub shafts 26 iournaled inbearings'27 carried within the supporting arms 20, 20. The shovel 7 is provided with an inclined plane surface 28 extending completely across the shovel frame, and the shovel blade, during operation thereof, rests upon and slides over this plane surface as will be hereinafter described. In this illustrative construction the parallelarms 20, 20 are pivotally connected at 29, on bearing sleeves supported by stub shaft-s or crank pins 30 formed on a pair of cranks 31, 31. As shown most clearly in Fig. 5, the inner ends of these cranks are keyed at the ends ofa horizontal shaft 32 extending transversely of, and suitably ournaled within the frame 4.

Various devices may be employed for effecting swinging of the cranks to thereby effect swinging of the arms 20, 20. and herein is shown a pair ofchain sprockets 33, 33 fixed at the opposite ends of the shaft 13 (see Fig. 3) and these sprockets are connected by endless transmission chains 34 to a pair of sprockets 35, 35 keyed at the opposite ends of a horizontal shaft 36. In the present instance, this shaft is arranged parallel with and above the shaft 32 and likewise suitably journaled within the frame 4 and extends transversely between the top and bottom flights of the gathering. conveyor 8, as clearly shown in Fig. 5. The sprockets 35 drivejthe shaft 36, and fixed at the ends of this shaft is a pair of spur gears37, 37 meshing with spur gears 38, 38 keyed at the ends of the transverse shaft 32 to which the cranks 31 are also fixed. It will thusbe seen that as the conveyor 8 is rapidly circulated within its guides, the cranks 31 are simultaneo'usly turned about their axes through the chain and sprocket connections 33, 34, 35 and the trains of spur gears 37,38. 'Herein keyed to the crank pins 30 are chain sprockets 39, 39 which drive through endless transmission chains 40, 40

housed in the arms 20, 20, sprockets 41 1 fixed, as shown in Fig. 4, to ashaft 42, jouraxes, an oscillatory swinging motionis im.-

parted to the arms 20,20 thereby causing the shovel blade 22 to be reciprocated back and forth over the planesurface 28 of the shovel 'while at the same time the shovel blade will be given a rotative motion through the sprockets 39, chains 40, sprockets 41," 43, chains 44 and sprockets 45 fixed to the opposite ends of the shovel blade, the shovel blade being rotated one-half a revolution upon each complete revolution of the cranks 31.

Fromthe foregoingit will be seenthat as the shovel blade is rotated'about its own axis it is at the same time given a linear motion back and forth relative to the shovel .90 by the swinging arms 20, 20. When the arms are in the full line position shown in 1 Fig. 6,'they are moved forwardlyfby the cranks which turn in, a clockwise direc.

tion as viewed in Fig. 6, but relatively slow ly due to theangular position of the cranks at that time. tively great penetrating power. sition, as indicated at A in Fig. 6, the forward penetrating edge of the shoveliblade has already entered beneath the material to be loaded and has started in lift up at its forward edge. The forward edgefl-of the There is therefore compara shovel blade moves upwardly untilit as sumes the position indicated at B in F ig.

mitting the -material to be discharged from the shovel blade onto the conveyor. v shovel blade moves from position C to position' D, the angular movement'of the shovel blade will again .be relatively fastand the linear motion will change directionso that the shovel blade will then move forwardlyalong the shovel. While the shovel blade m'oves forwardly from position C to posi tion A, thelower and forward penetrating edge of the blade scrapes over the plane surface 28 of the shovel and the'bladeis in such position where it will meet the least resistance when the, shovel blade is forced under the pile ofmaterial. It will thus be seen that a shoveling motion is transmitted to the shovel blade so that the blade is.

moved forwardly beneath the material, then lifted upwardly, moved rearwardly like. a

In the use of the improved material gathering means, the machine is propelled bodily along the trackway, the shovel frame 6 being in its downward position as shown in Fig. 2 at that time, to force the shovel 7 i into the pile of material. Simultaneously the shovel blade 22 is actuated to dig'beneath the material, lift the material upwardly and rearwardly onto the-shovel and thereafter to. discharge the material onto the elevating conveyor 8. -When' standing coal is encountered, that'is coal which has been shot down but notsufiioiently shattered to permit easy gathering thereot, the gathering mechanism is-ope'rated to undermine the standing cool,
